8 Adding and Replacing Hardware
This section provides procedures for adding and replacing components in your Avid
ISIS 5500 | 5000. Do not add any hardware if there are any issues with the system. Correct all
problems before adding new hardware and making changes to the system, perform a quick
checks to be verify that the system is in good working order, see “Health Check” on page 119.
Removing and Replacing Data Drives
The Avid ISIS automatically uses the spare drive in the Engine to repair the RAID group where
the drive has failed or was taken offline.

You do not need to stop the System Director to replace a single drive.
As long as you have a spare drive in the Engine the RAID controller automatically starts
repairing a RAID group using the spare when:
The RAID controller identifies a drive has failed.
A data drive has been taken offline (Make Drive Offline) using the LSI MegaRAID Storage
Manager.
A data drive has been physically pulled from the Engine (without being identified using one
of the two previous conditions).
Removing a Drive
When a RAID data drive fails, the ISIS 5500 | 5000 automatically replaces the failed drive in the
RAID set with the hot spare. You can identify the failed drive by locating the data drive on the
front that has both the blue and red LEDs on solid, for a list of data drive LED meanings, see
Avid ISIS Front Panel” on page 14. When you have a failed drive, the Status section in the
Management Console displays yellow and states the drive set is rebuilding with the percentage of
how much of the RAID set rebuild is completed. You can remove the failed RAID data drive
whenever the red and blue LEDs have indicated that the drive has failed. The rebuild process
does not need to be completed before the failed drive can be removed. The status remains yellow
until the rebuild is finished and a new hot spare has been inserted. When the new hot spare is
inserted, the ISIS 5500 | 5000 automatically makes the raw drive into a spare.
